-    \class QAssistantClient
-    \obsolete
-    \brief The QAssistantClient class provides a means of using Qt
-    Assistant as an application's help tool.
-
-    \ingroup helpsystem
-
-    \bold{Note:} \e{This class is obsolete and only required when using
-    the old Qt Assistant, now called assistant_adp. If you want to use
-    the new Qt Assistant as a remote help viewer, simple create a
-    QProcess instance and specify \tt{assistant} as its executable.
-    The following code shows how to start Qt Assistant and request a
-    certain page to be shown:}
-
-    \snippet doc/src/snippets/code/tools_assistant_compat_lib_qassistantclient.cpp 0
-    
-    \e{For a complete example using the Qt Assistant remotely, see the \l
-    {help/remotecontrol}{Remote Control} example.}
-    
-    In order to make Qt Assistant act as a customized help tool for
-    your application, you must provide your application with a
-    QAssistantClient object in addition to a \l
-    {assistant-manual.html} {Qt Assistant Document Profile} (\c .adp
-    file) and the associated documentation.
-
-    Note that the QAssistantClient class is not included in the Qt
-    library. To use it you must add the following line to your pro
-    file:
-
-    \snippet doc/src/snippets/code/tools_assistant_compat_lib_qassistantclient.cpp 1
-
-    A QAssistantClient instance can open or close Qt Assistant
-    whenever it is required.
-
-    Once you have created a QAssistantClient instance, specifying the
-    path to the Qt Assistant executable, using Qt Assistant is
-    simple: You can either call the openAssistant() slot to show the
-    defined start page of the documentation, or you can call the
-    showPage() slot to show a particular help page. When you call
-    openAssistant() and showPage(), Qt Assistant will be launched if
-    it isn't already running. When Qt Assistant is running, the
-    isOpen() function returns true.
-
-    When calling showPage() the Qt Assistant instance will also be
-    brought to the foreground if its hidden. The showPage() slot can
-    be called multiple times, while calling openAssistant() several
-    times without closing the application in between, will have no
-    effect.
-
-    You can close Qt Assistant at any time using the closeAssistant()
-    slot. When you call openAssistant(), or you call showPage()
-    without a previous call to openAssistant(), the assistantOpened()
-    signal is emitted. Similarly when closeAssistant() is called,
-    assistantClosed() is emitted. In either case, if an error occurs,
-    error() is emitted.
-
-    One QAssistantClient instance interacts with one Qt Assistant
-    instance, so every time you call openAssistant(), showPage() or
-    closeAssistant() they are applied to the particular Qt Assistant
-    instance associated with the QAssistantClient.
-
-    Qt Assistant's documentation set can be altered using the command
-    line arguments that are passed to the application when it is
-    launched. When started without any options, Qt Assistant displays
-    a default set of documentation. When Qt is installed, the default
-    documentation set in Qt Assistant contains the Qt reference
-    documentation as well as the tools that come with Qt, such as \QD
-    and \c qmake.
-
-    Use the setArguments() function to specify the command line
-    arguments. You can add or remove documentation from Qt Assistant
-    by adding and removing the relevant content files: The command
-    line arguments are \c {-addContentFile file.dcf} and \c
-    {-removeContentFile file.dcf} respectively. You can make Qt
-    Assistant run customized documentation sets that are separate from
-    the Qt documentation, by specifying a profile: \c {-profile
-    myapplication.adp}. The profile format can also be used to alter
-    several of Qt Assistant's properties such as its title and
-    startpage.
-
-    The Documentation Content File (\c .dcf) and Qt Assistant
-    Documentation Profile (\c .adp) formats are documented in the \l
-    {assistant-manual.html}{Qt Assistant Manual}.
-
-    For a complete example using the QAssistantClient class, see the
-    \e{Simple Text Viewer} example. The example shows how you can make
-    Qt Assistant act as a customized help tool for your application
-    using the QAssistantClient class combined with a Qt Assistant
-    Document Profile.
